Question 2
  • The following items are added to a test tube and
    allowed to stand for 45 minutes
  • 2 ml of IKI
  • 5 ml of distilled yeast culture after
    fermentation
  • 3 ml of 1.5M NaOH
  • Which of the following results would you expect?

Question 2
  • A brick red precipitate indicating the presence
    of a reducing sugar.
  • A white precipitate indicating the
    presence of CO2 gas.
  • A dark red colour indicating starch.
  • No precipitate because the reducing sugar will
    have totally fermented.
  • A yellow precipitate indicating ethanol.

Question 4
  • What does this diagram tell you about
    photosynthesis?

Question 6
  • What does this diagram tell you about
    photosynthesis?

Nothing. It tells you the the pigments of a leaf
absorb energy in the 400-500nm and 600 to 700nm
range

Question 5
  • One of the two yeast cultures you performed the
    iodoform test on produced alcohol. This
    production of alcohol involved which of the
    following steps?
